Product Properties
Clear, colorless, transparent oily liquid, odorlessKinematic viscosity: 300000 mm²/s (25℃)Outstanding viscosity-temperature performanceExcellent thermal and oxidation stabilityGood compatibility with silica, PTFE and other thickenersLow volatility under continuous high-temperature conditionsGood lubricating property and chemical inertnessResistant to oxidation and hardly generates carbon residues
Core Advantages
- Stable viscosity in wide temperature range, guarantee consistent performance of finished silicone grease
- Superior heat resistance, applicable for long-term high-temperature working conditions
- Good miscibility with common thickeners, easy for grease production and processing
- Low volatility, effectively reduce oil separation of silicone grease
- Excellent anti-oxidation performance, extend service life of lubricating grease
- Chemically inert, non-corrosive to metal substrates
Main Applications
300000cst Dimethyl Silicone Oil acts as ultra high viscosity base oil for special grease.Typical applications: raw material for high-temperature silicone grease manufacturing, base stock for vacuum sealing grease, thick silicone compound formulation, anti-friction grease for slow-speed heavy-load parts, insulating lubricating paste raw material, special damping silicone compound preparation.
Usage Guidance
Can be heated moderately to reduce viscosity during mixing with thickeners.Carry out small-batch formulation test before formal mass production of silicone grease.Avoid mixing with mineral oil or other non-silicone lubricants arbitrarily.Prevent moisture and dust contamination during production and storage.Keep away from strong oxidants in processing environment.
Packing & Storage
Standard package: 25kg plastic drum; small test samples are available.Keep container tightly sealed. Store in cool, dry and ventilated warehouse. Keep away from open flame, high temperature heat sources and strong oxidants. Prevent water and impurities contamination during transportation.
